DARLINGTON, S.C.—A postrace scuffle erupted between the crews of Kurt Busch and Ryan Newman at Darlington Raceway Saturday night after Busch nearly hit members of Newman’s crew with his car on pit road.

Busch and Newman both were involved in a wreck on lap 361 of the Bojangles Southern 500. Newman’s Stewart-Haas Racing team was upset about the way Busch left his pit stall after the wreck, nearly hitting members of Newman’s team.

Busch, who was running near the top 10 when he crashed, was upset after the wreck, showing his anger on his team radio.

Following the race, Busch ran into the back of Newman’s car on pit road. Newman got out of his car and walked away, but some members of Newman’s pit crew were there to meet Busch.

A shoving match ensued, causing a NASCAR official to fall onto the hood of Busch’s car.

Newman gasman Andy Rueger was called to the NASCAR hauler after the incident. Penalties could be handed down next week.

“It’s bad enough doing normal pit stops, it’s dangerous enough doing that,” Newman crew chief Tony Gibson said. “When you come ripping through somebody’s pit box like that, he could have took out five or six guys, plus the officials.

“I don’t know how somebody didn’t get run over, to be honest with you. It’s just a miracle nobody got hit. NASCAR is taking care of it and we’re all good and we’ll go on.”

NASCAR officials had talked to Newman, Gibson and Rueger after the race but had not talked with anyone from Busch’s Phoenix Racing team.

“We talked to Newman a little bit and he talked to Kurt afterwards and Kurt said he didn’t mean to hit him on pit road—he was taking his helmet off and looked up and he ran into the back of him,” NASCAR Vice President of Competition Robin Pemberton said.

“Right now, that is all the facts that we have.”

Pemberton said NASCAR officials did not complain about contact getting shoved during the scuffle.

“We didn’t see it that there was anything aggressive towards one of our officials,” Pemberton said.

Phoenix Racing crew chief Nick Harrison said he knew Newman’s crew would be looking for Busch after the race.

“It’s great for our sport—if they’re mad and want to fight, so be it,” Harrison said. “It is what it is. We’re here racing with Kurt Busch, we’re going to defend Kurt Busch and that’s our job.

“If you go anywhere racing in any part of America and you don’t back your driver up, you don’t deserve to be there with that driver and that’s how we take it.”

Busch, the 2004 series champion has a history of reacting angrily when things don’t go his way. He was released from Penske Racing after last season following a series of emotional outbursts during the season, including a confrontation with an ESPN reporter during the season finale.

"It's easy to say that Kurt blew a fuse again," Newman told SI.com. "I'm not sure why he did it and tried to run over our guys and NASCAR officials. And nobody is. I think the chemical imbalance speaks for itself.

"Kurt drilled me in pit lane and said that he was taking his helmet off, and he didn't see where he was going. I'm pretty sure there were 42 other guys that are taking their helmets off and doing whatever for the last 10 years, and that's the first time that's happened to me.

"Circumstances I think are that he lied and was so frustrated that he doesn't know how to deal with his anger."
